Ukraine’s vice prime minister and minister of digital transformation, Mykhailo Fedorov, asked major cryptocurrency exchanges on February 27, 2022, to block addresses associated with Russian users as Ukraine resisted Russia’s invasion.
Fedorov’s public request went further than freezing property belonging to named sanctioned people. He argued that exchanges should restrict ordinary users as well as addresses connected to Russian and Belarusian political figures. The statement did not identify a legal instrument, provide a list of accounts or explain how platforms should determine which blockchain addresses belonged to Russian users.
That distinction mattered. The request was an appeal from a senior Ukrainian official, not an order shown to be binding on every international exchange.
A request beyond targeted sanctions
Governments had already begun imposing targeted financial restrictions after Russia launched its full-scale invasion on February 24, 2022. The U.S. Treasury announced measures against major Russian financial institutions and designated Russian officials and elites. Fedorov’s February 27 request posed a broader question: whether private crypto businesses should deny service according to nationality even when individual customers had not been named under sanctions.
Centralized exchanges occupied an important middle ground. They maintained customer accounts, held assets for users and commonly collected identity information. Those operational features gave them the ability to suspend accounts or prevent withdrawals in ways that a permissionless blockchain generally could not.
Fedorov’s wording about blocking “addresses” nevertheless left a technical ambiguity. A Bitcoin or Ethereum address does not inherently disclose its owner’s nationality. An exchange could identify customers from its records and restrict their custodial accounts, but it could not prevent an unidentified person from creating a self-hosted wallet or receiving a valid transaction directly on a blockchain.
Crypto’s two roles in the conflict
The appeal arrived while Ukraine was using the same networks to receive support. On February 26, official Ukrainian accounts published Bitcoin and Ethereum donation addresses, with the Ethereum address also accepting the ERC-20 version of Tether’s USDT. By February 27, those wallets were attracting substantial public attention and millions of dollars in reported transfers.
The two developments placed crypto infrastructure on both sides of the same policy problem. Open networks allowed donors to send assets across borders without first obtaining permission from a bank. Centralized exchanges, meanwhile, remained identifiable businesses with custody systems, compliance teams and connections to conventional currencies.
Fedorov’s request therefore did not demonstrate that cryptocurrency itself could be switched off for a country. It demonstrated that exchanges could be pressured as financial gatekeepers even when the underlying networks continued processing valid transactions.
What remained unresolved on February 27
No verified event-day record established that the largest international exchanges had accepted the blanket request. Nor did the request prove that Russian individuals or institutions were using cryptocurrency to evade the newly announced sanctions. Transaction flows, ownership attribution and sanctions exposure were separate evidentiary questions that required more than nationality assumptions or visible blockchain activity.
There was also no reliable event-day measurement of the request’s effect on cryptocurrency prices or trading volumes. This reconstruction therefore makes no market-performance claim.
Later context
On February 28, Reuters reported that Binance would block accounts belonging to people targeted by sanctions but would not unilaterally freeze millions of Russian customers. Other exchanges also distinguished compliance with legally imposed sanctions from a nationality-wide prohibition. Those responses were not known outcomes of February 27, but they confirmed that Fedorov’s appeal had opened an immediate dispute over the power and obligations of centralized crypto platforms during war.
